In order to enable an iCal export link, your account needs to have a key created. This key enables other applications to access data from within Indico even when you are neither using nor logged into the Indico system yourself with the link provided. Once created, you can manage your key at any time by going to 'My Profile' and looking under the tab entitled 'HTTP API'. Further information about HTTP API keys can be found in the Indico documentation.

I have read and understood the above.

In conjunction with a having a key associated with your account, to have the possibility of exporting private event information necessitates the creation of a persistent key. This new key is also associated with your account and whilst it is active the data which can be obtained through using this key can be obtained by anyone in possession of the link provided. Due to this reason, it is extremely important that you keep links generated with this key private and for your use only. If you think someone else may have acquired access to a link using this key in the future, you must immediately remove it from 'My Profile' under the 'HTTP API' tab and generate a new key before regenerating iCalendar links.

Defining Sources Selection and Celestial Reference Frame Stability

Content

In a previous study, we characterized radio sources observed by Very Long Baseline Interferometry by different criteria in both radio and optical domains (see the abstract "VLBI sources in optical
and radio"). On the basis of the data derived from this study, we constructed several celestial reference frames by choosing a set of defining sources and studied their stability by two ways, statistically and temporally, inspired by Lambert [2013]. In parallel, a re-analysis of the ICRF2 was made, in the perspective of ICRF3 (expected date : 2018), to estimate its current stability and if it has changed since 2009, as it was the case for ICRF1 [ Gontier et al. 2001, Feissel-Vernier 2003, Lambert et al. 2008, Lambert & Gontier 2009 ] . Finally, an ambitious goal will be to develop by those works an automatic tool that will regularly analyse new VLBI observation sessions and will be able to alert the community on defining sources becoming potentially unstable.
